Nothing wrong with that!
I'm getting Thai massages almost every weekend, they cost me half an hour of teaching here.
But I'd rather do yoga, one session feels better than three good massages, plus it gives me a happy feeling afterwards because I did forced myself again through 90 minutes of sweating and rebuilding my body.
There's a lot of talk about the spiritual aspect of yoga but I started it because of constant back pain. The doctors recommended swimming, massages and a wedge-shaped pillow for my back to sit straight. It all didn't help much so I turned to yoga which definitely improved about everything, and concentrating on yourself for 90 minutes gives you an interesting feedback about what's going on with you, physically and mentally.
After ten sessions it was clear to me that I will do this type of yoga for the rest of my life.
